HEEL BUILDING AND PRESSING MACHINE.

To all whom it may concern:

Be it known that I, CHARLES O. Rrisnnc, of Brockton, in the county of Plymouth and State of Massachusetts, have invented Certain new and useful Improvements in Heel Building and Pressing Machines, of which the following is a specification.

This invention has for its object to provide a machine or appliance whereby pieced heel lifts may be assembled in heel form and coniined in their predetermined relation to each other and subjected to compressive pressure while paste or cement, applied to the lifts while they are being assembled, is setting or hardening.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings which form a part of this specification-Figure l represents a perspective view of a heel building and pressing machine embodying my invention7 parts being broken away and shown in section; Fig. 2 represents a top plan view of one of t-he lift-holding trays hereinafter referred to; Fig. 3 represents a section on line 3 3 of Fig. 1; and Fig. 4 represents a section on line 4 4 of Fig. 1, and shows in sect-ion a portion o-f the table and ga e hereinafter referred to.

Similar re erence characters indicate the same or similar parts in all the figures.

In carrying out my invention I provide a series of lift-holding trays, each adapted to support an assemblage 12 of pieced heel lifts and to guide the operator in properly assembling the pieces to form an assemblage having the desired heel shape. Each tray is referably made of sheet metal and has a at bottom 13, and a plurality of liftconfining walls 14, projecting above said bottom. In practice the flat bottom of the tray may be made up of a series of heelshaped sheet metal plates bent upwardly at their edges to form edge-confining walls 14, externally and internally curved ortions conforming to the curved edge o a heel lift, the whole forming an elongated tray of the general form illustrated in the drawings, each tray being independent of the others and the whole, when charged with heel lifts, being adapted to be superimposed on a press bed 15, to form a stack, as shown by Flg. 1.

provided with vertical slots 18 -which re-l 60 ceive clamping screws 19 engaged with the table 16.

When the gage 17 is adjusted to project 4 to the desired height above the table, one of the described trays is placed upon the table and caused to abut against the inner side of the gage. The operator then assembles the pieced heel lifts on the tray, the lifts being coated with cement. The height of the heel, or the thickness of the assemblage of lifts, is determined by the height of the gage 17, the operator building up the assemblages of lifts until the upper surfaces of the assemblages are iush with the upper edge of the gage, as shown by Fig. 4. .When the desired number of trays have been thus charged they are superimposed on the press bed 15 to form a stack as above stated! The bed 15 forms a part of a press adapted to exert vertical pressure on the stack t0 compress the lifts side-wise, thus reducing their thickness, and having means for exerting horizontal edge-wise pressure on the vertical sides of the stack to prevent edge-wise expansion or enlargement of the lift assemblages and to support the confining walls 14 of the trays so that they will not be caused to bulge outwardly by the vertical pressure exerted on the lifts.

As here shown, the press includes two fixed vertical walls 20, and 21, adapted to bear respectively on one of the longer vertical -sides and one of the shorter vertical sides or ends of the stack, a horizontally movable platen 22 adapted to bear on the opposite longer side of the stack, a horizontally movable platen 23 adapted to bear on the opposite shorter vertical side or end of the stack, and a ver-tically movable platen 24 adapted to bear on the top surface of the stack, each of said platens being provided with operating means such as a screw 25 engaged with the threaded orifice in a fixed support, as shown in Fig. 1, where the screw which supports the platen 22 is engaged with a threaded orifice in a fixed bar 26, while the screw which supports the platen 23 -is engaged with a threaded orifice in a fixed bar 27, and the screw which supports the platen 24 is enga ed with a threaded orifice in a fixed -ear or racket 28.

The pla-ten 22 is preferably removable from rthe press and from its operating screw to permit the insertion and removal of the trays and their contents. After a stack has been formed in the press, the platen 22 is inserted and brought to a suitable bearing on one of the longer sides of the stack, the platen 23 being also brought to a bearing on one of the shorter vertical sides or ends of the stack, suitable pressure being applied to said platens to force the remaining sides of the stack against the fixed walls 20 and 21. Vertical pressure is then exerted on the platen 24 to cause the compression of the lifts to the desired extent. The walls 2O and 21 and platens 22 .and 23 support the confining Walls 14 of the trays against the outward displacement, and prevent them from bulging outward under the vertical pressure exerted by the platen 24.

The platen 22 is preferably provided with a series of curved recesses 29 on its inner side to conform to the shape of the curved sides of the confining walls 14. The inner side of vthe platen 23 is also preferably curved at 30 to conform to the portion of the stack on which it bears.

The press body 15 is located in suitable proximity to the table 16 and gage 17 and is preferably screwed or otherwise aiiixed to a portion of said table as shown.

The sheet metal trays occupy relatively little space so that the maximum number of trays and lifts may be assembled in the press. Although the lift-conlining walls 14, when made of sheet metal, are flexible, their flexibility is compensated for by the contining walls and platens which support said walls against outward displacement so that they are fully as edective as they would be if the tray were of rigid construction and therefore much more bulky.

I claim- 1. A heel-lift press comprising a bed adapted to support a stack of superimposed lift-holding trays and their c-ontents, and means for exerting vertical and horizontal pressure on said stack to compress the assembled lifts sidevvise and prevent their edge- Wise expansion.

2. A heel-lift press comprising a bed adapted to support a stack of superimposed lift-holding trays and their contents, a vertically movable platen opposed to said bed and adapted to exert vertical pressure on said stack to compress the assembled lifts sidewise, and means for exerting horizontal pressure on the stack to prevent the same from expanding edgewise under the vertical pressure.

3. A heel-lift press comprising al bed adapted to support a stack of superimposed trays 'and their contents, a vertically movable platen opposed to said bed and ladapted to exert vertical pressure -on said stack to compress the assembled lifts sidevvise, fixed vertical walls adapted to support two of the vertical sides of the stack, and horizontally movable platens adapted to exert pressure horizontally on the other two sides of the stack.

4. A heel-lift-holding tray having a flat bottom of thin sheet material adapted to support a plurali-ty of heel lift assemblages, and a plurality of heel-shaped confining walls also of thin sheet material projecting above said bottom and adapted to bear on the edges of said assemblages, said tray Iand its contents being adapted to be assembled with other trays and their contents in a press to form a stack.

5. A heel-lift press c-omprising a bed adapted to support a stack of superimposed trays and their contents, each tray having a flat bottom,y adapted to support a plurality of heel lift assemblages, and a plurality of heel-shaped confining Walls, portions of which are curved both internally and externally, a vertically movable pla-ten opposed to said bed and adapt-ed to exert vertical pressure on said stack to compress the assembled lifts sideWise, fixed vertical walls adapted to support two of the vertical sides of the stack and horizontally movable platens adapted to exert horizontal pressure on the other two sides of the stack, one of said horizontally movable platens being provided with recesses conforming to the curved portions of the confining Walls of the trays.

In testimony whereof I have affixed my signature, in presence of two Witnesses.
